Phys.org / Much of Earth's 'space dust' may come from unidentified near-Earth asteroids
Like a shelf in an old house, the Earth collects a lot of dust from its surroundings. This "space dust" is mostly made up of micrometeorites that survive atmospheric entry and provides researchers with a cheap and easy way ...
Phys.org / Scientists just measured the smallest possible contacts for future computer chips
The rise of AI has created an almost insatiable appetite for computing power. Training and running AI systems requires vast numbers of transistors, and engineers are now racing to pack more of them onto every chip. With their ...
Phys.org / H5 bird flu detected in Australian seabird for first time
Scientists have detected the highly contagious H5 bird flu in an Australian seabird for the first time, the government said Friday.
Medical Xpress / Epigenetic mapping provides deeper insight into leukemia
Researchers at Karolinska Institutet in Sweden and Kyoto University in Japan have identified new subgroups of the blood cancer acute myeloid leukemia. The study, published in the journal Nature, shows that changes in the ...
Phys.org / What to know about the total solar eclipse due in August
Day will briefly turn into night across a swath of northern Spain on Aug. 12, when the moon will completely cover the sun during a rare total solar eclipse.
Medical Xpress / New mechanism explains how nerve cells form one long output branch
DZNE researchers have uncovered a mechanism that determines why a neuron usually forms a single, long extension called an "axon"—a phenomenon that is fundamental to how our brain functions. Contrary to the common view that ...
Phys.org / AI can predict how you'll respond to a survey—but that's not the same as understanding you
What makes people change their minds or their behavior? Social scientists spend a lot of time thinking about this question, and experiments are one of the most powerful ways to answer it.
Phys.org / Baseline tool could separate alien life signals from geology on ocean worlds
When it comes to the search for life elsewhere in the universe, methane and other chemical compounds are seen as signs of biology because they are often produced by living microbes. However, scientists can be misled because ...
Medical Xpress / Most obesity drugs do not improve quality of life or heart health, analysis indicates
Despite substantial weight loss, most obesity drugs such as Wegovy and Mounjaro do not meaningfully improve quality of life, and few show cardiovascular benefits at one year, according to an analysis of the latest evidence ...
Phys.org / 'Cosmic wallflowers' may hold the key to the origin of globular clusters
Astronomers using computer simulations have investigated whether a class of star clusters nicknamed "cosmic wallflowers" could be the long-sought ancestors of the globular clusters we see orbiting galaxies today. Their paper, ...
Phys.org / NASA's New Horizons spacecraft wakes from its longest hibernation in good health
Following its longest hibernation period ever of nearly a year, NASA's New Horizons spacecraft has emerged in good health and is ready to begin transmitting science data gathered in the distant Kuiper Belt far beyond Pluto.
Science X / Your brain expects each face to move its own way, and notices when a smile breaks that rule
Imagine meeting someone new whose smile feels just a bit wrong. You might think, "this smile is too fast (or slow, or crooked)," even if the movement itself is common. How could your brain sense this subtle "offness" from ...
